A conceptual history of classification and phylogenetics, mainly as related to plants. Focuses on the early development of ideas within biosystematics, with accompanying illustrations. Networks are effectively treated as variants of trees.

A richly illustrated history of trees, with a few networks. Focuses on the illustrations, with some accompanying text. The best source to see what people have drawn in the way of trees, but weaker on networks.

In Japanese. Covers the development of the tree metaphor (with a few networks), as related to pedigrees, phylogenies, and knowledge representation in general. The breadth of the topic is indicated in the "mandala" of the title, which is "a generic term for any diagram, chart or geometric pattern that represents the cosmos metaphysically or symbolically".

A conceptual history of trees, with a few networks. Focuses on the development of the ideas, with accompanying illustrations. Starts with pedigrees, and proceeds from there to phylogenies. The best coverage of phylogeny concepts, but explicitly treats networks as "trees with reticulations".
